Note 1, Cooling Towers are non-permit required confined spaces for normal entries if the equipment is fully de-energized (LO/TO) per the applicable procedure. All electrical energy, make up supply water (if applicable) and chemical pumps (if applicable) to associated cooling tower equipment must be de-energized and controlled before entry. The cooling tower becomes permit required if any kind of welding, cutting or burning is completed or chemicals are used that release fumes or vapors within the cooling tower enclosure. Ventilate with portable fans as necessary to remove any fumes or vapors from work processes.

Note 2, Air Handlers are non-permit required confined spaces for normal entries if the equipment is fully de-energized (LO/TO) per the applicable procedure. The air handler becomes permit required if any kind of welding, cutting or burning is completed or chemicals are used that release fumes or vapors within the air handler enclosure. Ventilate with portable fans as necessary to remove any fumes or vapors from work processes.

Note 3, These areas are non-permit required confined spaces for normal entries if elevator equipment is fully de-energized (LO/TO) per the applicable procedure. The area becomes permit required if any kind of welding, cutting or burning is completed or chemicals are used that release fumes or vapors within the area.

Note 4, These areas are non-permit required confined spaces for normal entries if all equipment is fully de-energized (LO/TO) per the applicable procedure. All electrical energy, pumps (if applicable) and equipment with the potential to create a hazardous condition must be de-energized and controlled before entry. The area becomes permit required if any kind of welding, cutting or burning is completed or chemicals are used that release fumes or vapors within the area.
